Abstract
A catheter guidewire having a covering of a fluoropolymer tape. The tape may be applied either helically or longitudinally to the outer surface of the guidewire or to the surface of the wire from which the guidewire is made. Such a covering is inert, lubricious, flexible, will not flake, and can be applied as an extremely thin coating. Additionally, such a covering allows the guidewire to tolerate the application of greater force before uncoiling and wire breakage occurs. Other catheter guidewire devices having fluoropolymer tape coverings are also described.
Claims13
A catheter guidewire device comprising a first length of helically wound wire having a covering of a fluoropolymer tape, said catheter guidewire device having distal and proximal ends, wherein the first length of helically wound wire has adjacent windings which are in direct contact so long as tension is not applied to the catheter guidewire device between the distal and proximal ends.
A catheter guidewire device comprising a length of helically wound wire and an axially oriented safety wire within the helically wound wire, said safety wire having a covering of fluoropolymer tape.
